This invention relates to new and useful improvements in machines for treating fur either to carrot or dye it.

An object of the invention is to provide a machine for the purpose stated and which includes means for spraying the carroting or dyeing material on to the fur, said means being so arranged as to prevent drops of the material getting onto the fur.

Another object is to provide a carroting or dyeing machine wherein the carroting or dyeing material is sprayed onto the fur to be treated, means being provided whereby the angle of the spray relative to'the fur may be changed as and when required.

A further object is to provide a carroting or dyeing machine including means whereby the carroting or dyeing material is sprayed through the use of compressed air, means being provided whereby the position of the spraying means may be adjusted either to vary the angle at which the spray is applied to the fur or to vary the position o the spraying means relative to the fur.

A further object is to provide a carroting or dyeing machine including meansfor feeding a liquid carroting or dyeing material to a point above the fur to be treated, and including means directing-compressed air beneath the point of delivery of the liquid whereby the liquid is taken up by the air spray and drops of the liquid prevented from getting on to the fur.

An additional object is to provide a fur carrotinrr or dyeing machine including means for applying a continuous spray across the entire width of the fur bearing skin whereby the fur is uniformly' treated.

Other objects and advantages will become apparent from a consideration of the following detaileddescription taken in connection with the accompanying drawing wherein one satisfactory embodiment of the invention is shown. However, it will be understood that the description and drawing are for the purpose of disclosure and that the invention is not limited to the details shown, since changes in construction, combination and arrangement of parts may be made without departing from the spirit of ythe 'invention or theA scope of the appended claims to which reference mustbe had for a definition of the limitations of the invention.

In the drawing:

Fig. 1 is a central longitudinal sectional 55 view substantially on the line 1-1 of Fig. 2;

Fig. 2 is a plan view of the entire machine, a section of the air drum of the spraying means being cut away;

Fig. 3 is a detail sectional view of a por- 60 tion of the means for supplying air to the spray, the view being taken substantially along the line 3 of Fig. 1; and

Fig. 4 is a side elevational view showing some of the driving mechanism used in the 85 machine.

Referring in detail to the drawing, the operating parts of the machine are shown as mounted upon `a table or support 5 including supporting-legs 6 and 7, side rails 8 70 and 9, andl supporting surfaces 10 and 11 extending between and secured to the side rails 8 and 9.- At the rear edge of the supporting surface or top 10 are a pair of corrugated feed rolls comprising upper and lower rolls 12 and 13 driven from a suitable source of power as will presently be described. I

Spaced rearwardly of the rolls 12 and 13 `are a' pair of feed rolls comprising upper and lower corrugated rolls 14 and'15 respectively... As shown the upper rolls 12 and 14 have their shafts 16 and 17 lrespectively, disposed to operate in suitable bearings 18 secured on the upper edges on the side rails 8 and 9. Thus it will be seen the feed rolls span the space between the rails 8 and 9. The lower feed rolls 13 and 15 are mounted to align with the upper feed rolls 12 and 14 respectivelya-nd these lower feed rolls are also mounted in the side rails 8 and 9 by any suitable means.

Mounted between the front and rear sets of feed rolls is a sheet or plate of glass 19, 95 this sheet or plate substantially filling the space between the sets of feed rolls and extending from one of the side rails 8 and 9 to the other thereof. Any suitable means may be used for vmounting the plate 19. As shown this means includes brackets 29 secured to the rails 8 and 9 as by means of screws 21.

A pair of brackets 23 and 24 are mounted on the rails 8 and 9 rearwardly of the feed roll 14. These brackets are somounted as to have a limited movement longitudinally of the rails and to this end each of the brackets is slotted as at 25 and secured to its respective rail by means of a bolt 26 carrying a nut 27. As shown the rails 8 and 9 have greater height adjacent their rear ends whereby shoulders 28 are formed. Each of these shoulders 28 carries a short forwardly projecting pin 29 and a corresponding pin 30 is carried by the upwardly extending rear portion 31 of the brackets 23 and 24. Interposed between the shoulders 28 and the portions 31'of the brackets, and having their end prtions disposed about the respective pins 29 `and 30 are a I pair of coil springs 32. These springs 32 normally urge the brackets 23 and 24 in the direction of the feed roll 14 and permit of movement in said brackets in ay direction p away from the feed roll.

At its forward end each of the brackets 23 and 24 carries an upstanding portion 33 reinforced by web 34 as shown. The upper ,ends of the portions 33 are enlarged to provide bearings 36 wherein are mounted the end portions of a shaft 37 carrying a roll 38. In the art this roll 38 is known as a slicking roll. Roll 38 is driven from the shaft 17 of the roll 14 and as shown Athe driving means includes a relatively` lar e pulley 39 on the shaft 17 and a relative y small pulley 40 on the shaft 37, an endless belt 41 being disposed over the two pulleys. Owing to t e difference in the size of the pulleys 39 and 40 it will be apparent that roll 38 will be driven faster than will the roll 14, and `the purpose of this difference in speed will later be described in detail.

The driving means for the different parts.

may comprise an arrangement as shown although it will be understood that different lay-outs for this purpose could be used. From any suitable source of power the shaft 42 is driven and this shaft carries a set of pulleys 43 of different sizes. Above the shaft 42 and supported by the side rail 9 is a relatively short shaft 44 provided with a set of pulleys 45, the pulleys of the set 45 being arranged in reverse relation to the pulley of the set 43. An endless belt 46 is used for transmitting power from the pulleys 43 to the pulleys 45 and it will be apparent that the belt may be shifted on the pulleys to have the shaft 42 drive the puleys 43 at the desired speed.

Secured to the shaft 44 inwardly of the pulleys 45 is a gear 47 relatively small in diameter and meshing with and driving gears 48 and 49 secured to the shafts 16 and 17 of the rolls 12 and 14 respectively.

The pulleys and gearing just described are rail. 9. At the outer .side of the rail 8the shafts 16 and 17 carry gears 50 and 51 respectively, these gears 50 and 51 meshing with and driving gears 52 and 53 arranged on the ends of the shafts of the rolls 13 and 15 respectively wherebyY such rolls are driven in a direction opposite to that in which the rolls 12 and 14 are driven.

Secured to the rear support or table 11 are uprights 54 three of which are shown. These uprights support a receptacle 55 into which is received the neck 56 of a container or bottle 57 carrying the carroting or dyeon a rubber or other supporting ring 58 which is constructed to permit entrance of air, and it will be understood that since a llexible tube or pipe 59 is fed from the receptacle 55, as through the opening 56, there will be a steady flow of li uid to such tube or pipe under a constant ead .or pressure. At its forward end the tube 59 isprovided with a T-shaped fitting 61, the branches of which are connected to other sections of flexible tubing 62 and 63 respectively. 'A tube 64 preferably of glass is disposed transversely`of the support and above the glass plate l19, the tube above such plate having at its under side a series ofl perforations 65.

Brackets 66 are secured to the end portions of the supporting surface or top 10. The brackets are adjustable and to this end each bracket is slotted at 67v for the reception of a bolt 68 carrying a nut 69 by means of which the brackets may be clamped in adjusted positions. As shown the brackets incline at 70 as they extend rearwardly and at its yrear end each bracket has an opening for thev reception of a stud or short sh'aft 71 carried by the cap or closure 72 of a relatively large tube 73. It will be understood that owing to its particular mountinflr in the brackets 66 the tube may be rotated and la screws or other means 74 are provided or securing the tube in desired adjusted position.

By means of brackets 75 the'glass tube 64 may be secured to and su ported by the relatively large tube 73. ompressed air is supplied to the tube 73 throughv theexible piping or tubing 76. Extending through a wall of the tube 73 are a series of small tubes 77 each having its inner end open as at 78 and each in a side wall of its outer end portion being an orifice 79. There is one tu e 77 provided for each of the openings or orifices 65 in'the tube 64 and the tubes 77 are, so arranoed that their openings-0 1` orifices .79 are isosed slightly beneath thel openings or orices 65 of the tube 64. With the construction described it will be understood that the air pressure throughout the tube 73 will shown as arranged at the outer side of the l rovided with be the same and that accordingly the air issuing through each of the orifices 79 of the tubes 77 will be under the same pressure.

A conveyor in the form of an endless belt 80 operates to receive the carroted or dyed furs and carry them from the machine. This belt 80 operates over a roll 81 secured in a bearing member 82 carried by the underside of the rails 8 'and-9. The belt 80 also operates over a roller 83 mounted in bearings in brackets 84 secured to the upright 7. The roller 83 has its shaft 85 extending beyond one of the brackets 84 and carrying a pulley 86 over which is trained a driving belt 87 driven as by a pul1ey'88 on the end of the shaft 16. It will be noted that the conveyor 80 extends rearwardly of the feed rolls 14 and 15 and when treated furs pass from these rolls they will be received on the conveyor and delivered by the latter to a second conveyor if desired or to a receptacle 89.

In the operation of the improved machine furs are fed either by hand or otherwise across the support 10 to the first set of feed rolls comprising the rolls l2 and 13. For the purpose of the present machine the skins are fed with their fur side up and as they are pushed along or fed along across the plate 19 by the rolls 12 and 13 they are sprayed with the carroting or dyeing material. Owing to the use of a plurality of openings'or orifices infthe tubes 64 and in f' the tubes 77 the treating material'is applied to the furs in the form of a sheet of mist. Owing to the angle at which the spray is applied it gets under the fur fibres raising them up as suggested in the drawing.

whereby the material penetrates to the roots of the fibres. Since the sheet of mist or the spray is substantially the width of the plate 1S) and of uniform pressure throughout it.

will cover the entire width of the fur bearing skin and accordingly the fur will be uniformly treated.

Since the air orifices 79 in the tubes 7 7 are disposed below the orifices in the tubes 64 for the liquid it will not be possible for drops of the carroting or dyeing liquid to fall onto-:the furvand burn it, as such drops would be required to pass through a continuous air blast. This air picks up and finely divides any liquid dropping into it. VVit-h our present arrangement the jets of air extend below and across the orifices 65 and accordingly all of the liquid is taken up in the air. This is an important feature of our device as giving a uniform treatment to the fur and preventing damage to it by too much carroting liquid at any spot. After the treated furs pass across the plate 19 they are engaged by the feed rolls 14 and l5 and drawn along beneath the spray. Should a fur bearing skin tend to turn upwardly with the upper feed roll 14 it will be pushed back off such roll by the slicking roll 38 which as previously described rotates at a higher speed than does the feed roll.

Since the slicking roll -is resiliently mounted due tothe employment of the springs 32 it may move toward and from the feed roll to accommodate furs of difi'er- 'rolls 14 and 15 they will fall down onto the conveyor 80 and be carried from the machine in a manner already described.

Owing to the fact that the material used in treating the furs may be poisonous and corrosive and to prevent the spread of the sprayed material where it might be inhaled by the workmen the entire machine is enclosed in a glass case or housing (not shown). Also, while the machine has been described as for the purpose of carroting or dyeing furs and particularly with relation to carroting, it is to be understood that the invention is not limited to the particular uses stated and further that while the invention is shown as being used on fur bearing skins some features of it would be applicable to the treating of fur after the same has been removed from the skin. Therefore, wherein the following claims the machine is described as a carroting machine it is to be understood that it is intended to cover the machine for other purposes.
